Abdel Fattah al-Sisi has been sworn in for a second term as Egypt's president with a vow to fight "those who choose violence, terrorism and extremism", APA reports quoting BBC.
Fighter jets flew overhead and there was a 21-gun salute as Mr Sisi took his oath in parliament.
Mr Sisi won 97% of the vote in March but on a turnout of just 41% and with his only opponent a Sisi supporter.
Supporters say he has brought much-needed stability, opponents that he has stifled democracy with arrests.
Egyptian air force fighter planes flew overhead releasing smoke in the colours of the national flag as Mr Sisi, 63, approached parliament in his motorcade.
After taking the oath of office he said in his speech he wanted to create a "common space" for Egyptians and that only those "who chose violence, terrorism and extremist thought as a way to impose their will" would be excluded.
The president has faced a series of jihadist attacks that have killed hundreds of military personnel and civilians, many of them in the northern Sinai peninsula.
Mr Sisi also said: "Together we face economic, social and political challenges and their negative effects on all aspects of life."
Although GDP has risen in the past year, economic recovery remains fragile and cuts to subsidies have proved unpopular. Egypt took a $12bn (£9bn) IMF loan in December 2016.
The retired field marshal led the military's overthrow of Egypt's first democratically elected president, Mohammed Morsi, in 2013 following protests against his rule.
Since then, he has overseen what human rights groups say is an unprecedented crackdown on dissent that has led to the detention of tens of thousands of people.
Activists have accused Mr Sisi of carrying out a wave of arrests targeting opponents since the election.
They say dozens of people have been detained on charges including spreading fake news and belonging to illegal groups. One arrested last week was the activist and blogger Wael Abbas.
